15.2 -Flip-Flops and De Morgan’s Laws

In the context of Boolean algebra, what does the first De Morgan’s theorem state?

• The negation of a conjunction is the disjunction of the negations
• The negation of a disjunction is the conjunction of the negations
• The result is always true
• The theorem only applies to three variables

Which of the following applications can flip-flops be used for?

• Memory storage
• Data counters
• Arithmetic operations
• Network routing

What is the truth table for a JK Flip-Flop when both J and K are 1?

• The output toggles
• The output is set to 0
• The output is set to 1
• The output remains unchanged

What are the two main inputs for an SR Flip-Flop?

• Set and Reset
• Clock and Reset
• Set and Toggle
• Set and Clear

How does a JK Flip-Flop differ from an SR Flip-Flop?

• JK Flip-Flop can toggle states
• JK Flip-Flop has asynchronous inputs
• JK Flip-Flop avoids indeterminate states
• JK Flip-Flop has only one input

Which of the following statements correctly describes De Morgan’s Laws?

• They transform AND into OR operations
• They simplify Boolean expressions
• They require three inputs to function
• They are only applicable in digital circuits

What is the output of a JK Flip-Flop when J=1 and K=0?

• Output Q will remain unchanged
• Output Q will be set to 0
• Output Q will toggle
• Output Q will be set to 1

What happens when both inputs of an SR Flip-Flop are high?

• It sets the output to 1
• It maintains the previous state
• It resets the output to 0
• It enters an indeterminate state

How do De Morgan’s Laws assist in simplifying complex logic expressions?

• They convert AND operations to OR operations
• They allow for negation of inputs and outputs
• They make expressions more complex
• They require additional variables

What is the output of a JK Flip-Flop when J=0 and K=1?

• Output Q will be reset to 0
• Output Q will toggle
• Output Q will be set to 1
• Output Q will remain unchanged
